This is one of those works with a unique, more organic type of technique. The 'moss' looks airbrushed on, and contrasts with - and seems to be overtaking - the more typical, and washed out, rusted, traditional framework. The black backgrounds are shaded in such a way so as to seem like foregrounds against the even further-back lightened areas to be overtaken, leading this work to an unconventional and unique overall presentation.
